Blogshares has created a stock market for people to invest in potentially aggresive shares - aggressive blogs are those that are basically incoming links from other sites hence these links in turn lends credability to the actual blog.
BlogShares is a fantasy stock market for weblogs. Players get to invest a fictional $500, and blogs are valued by incoming links.
Personally I dont see anything positive coming out of this - except for that fact that my blog started off at B$ .15 and landed at B$ .41 in a span of 2 months a significant rise to my original share value - with the so called money, I in turn invested into by blog buddy G3nu1n3 and his price rocked up to B$ .62
Have a look at your own blog and see if its worth shit - mine is ;)
